In this study, 45 (10 whole specimens and 35 frozen claws) frozen samples of Portunus pelagicus imported into Sicily (Italy) from the west coast of Africa were examined to assess their bacteriological characteristics and suitability for consumption. Bacteriological examination was performed on two subsamples for each whole crab. The first was the body and claw muscle; the second was a pool of viscera and gills. In the case of frozen claws, each muscle claw was a sample. An aerobic plate count at 30°C (mesophilic aerobic plate count [MAPC]) and 18°C (psychrotrophic aerobic plate count [PAPC]) for 3 days, sulfite-reducing anaerobes, total coliforms, Escherichia coli, enterococci, and Aeromonas spp. were enumerated. Detection of halophilic Vibrio spp. was also performed using salt polymixin broth as an enrichment medium and thiosulfate citrate bile salts sucrose agar as a selective medium; a further morphological and biochemical identification of suspected colonies was performed. The bacterial load of muscle and viscera and gills was low. The MAPC ranged from 0.78 to 3.26 log CFU/g, and the PAPC ranged from 0.48 to 2.41 log CFU/g. Vibrio spp., Aeromonas spp., sulfite-reducing anaerobes, and E. coli were never isolated from muscles or viscera and gills. In contrast to the findings of others, this study showed good bacteriological quality of crabs imported into Sicily from the west coast of Africa. This study also demonstrated the positive influence of the characteristics of environment of origin and postharvest handling hygiene; these parameters could be useful in the context of the application of the hazard analysis critical control point system to this production.

Geological Features

Twenty years ago the region now included in the Province of British Columbia was—with the exception of the coast-line— little known geographically, and quite unknown geologically. From the days of Cook and Vancouver, and the old territorial disputes with the Spaniards, this part of the west coast of North America attracted little attention till the discovery of gold in 1858. As among the first in the field geologically may be mentioned Dr. Hector and Messrs. H. Bauerman and G. Gibbs. The observations of these gentlemen, though bringing to light many facts of interest, were confined to a comparatively small part of the area of the province, and it was not till the inclusion of British Columbia in the Dominion of Canada in 1871 that the systematic operations of the Geological Survey of Canada were extended to this region. Since this date a number of reports treating of the geology of British Columbia have been published, and on these, together with a personal knowledge of the country, obtained during five seasons' work in it in connexion with the Survey, I shall chiefly depend in giving a brief account of the main geological features so far developed.

Among the Conchifera transmitted by M. Verbeek, is a specimen of Cyrena. The shell is certainly from a very modern formation, as it retains its translucency and traces of a pale buff colour externally.

Precambrian Terrain

The geological Survey of Greenland (GGU) was established in 1946 and its activities were initially concentrated on a hitherto relatively neglected part of Greenland - the Precambrian terrains of the central and southem west coast. Field work started in 1946 with reconnaissance mapping of the country between latitudes 69°N and 63°45'N on the west coast of Greenland under the direction of A. Noe-Nygaard and H. Ramberg. A reconnaissance map on a scale of 1:500 000 covering all areas accessibie from the coast was published in 1961 (Noe-Nygaard & Ramberg, 1961) with a brief description. Soon after the mapping started it became possibie to divide the northem part of the Precambrian terrain into a southern, older fold belt and a northem, younger belt (the 'Nagssugtoqides') on the basis of the deformation and metamorphism of a pre-Nagssugtoqidian swarm of basic dykes - the Kangâmiut dykes. These early results were published in a now c1assic paper by Ramberg (1948).

In 1955 Grønlands Geologiske Undersøgelse (The Geological Survey of Greenland, GGU) started the systematic mapping of the west coast of Greenland. Up to 1963 the work was concentrated in the southernmost part of Greenland, around Nanortalik:, Julianehåb and Ivigtut, from 1958 to 1963 from a base camp, 'Dyrnæs' near Narssaq. In 1964 the base camp was moved northwards to a site near Frederikshåb, 'Mellembygd', and from 1964 to 1968 the region around Frederikshåb was mapped, as far north as Frederikshåbs Isblink. In 1969 the base camp was moved still further north, to 'Midgård', 15 km north-north-east of Fiskenæsset, and in 1970 mapping in the Fiskenæsset Region commenced. Mapping of the area between Frederikshåbs Isblink and Fiskenæsfjorden (an area of about 2500 km2) is now almost finished, and a simplified map is presented on plate 1. This paper attempts to give an outline of the geology of the area.

We have heard today about the palaeomagnetic evidence which requires the magnetic pole to wander through the body of the Earth and at the same time the continents to wander over the surface of the Earth, since Mesozoic times. We have heard the geological evidence reiterated as evidence of continental drift. Others in the past have equally ably demonstrated that this does not need to be considered evidence of continental drift. We have seen the continents authoritatively reconstructed by a computer. This seems most convincing except of course it seems necessary to discard Central America, Mexico, the Gulf of Mexico, the Caribbean Sea and the West Indies, along with their pre-Mesozoic rocks! On the other hand we have seen evidence that the ocean crust too breaks into blocks which shift relative to each other by distances up to 1400 km. A series of transcurrent faults occur along the west coast of the United States. Unmentioned is the similar fault along the east coast which extends across 600 km of the continent and out into the sea, continuing, some think, across the Atlantic to the mid-ocean ridge. On land this fault has been dated as pre-Mesozoic. It is at the same latitude as the Mendocino Escarpment off the west coast but shows right lateral movement while the latter shows predominantly left lateral movement.

Shallow Geology

During August 2017, as part of the habitat mapping of Natura2000 areas, a geophysical survey of a large area within the Skagerrak was undertaken by the Geological Survey of Denmark and Greenland. In this article, we use the acquired data to discuss the geology of Tannis Bugt (Fig. 1), a large shallow bay at the north-west coast of Vendsyssel. The bay extends 40 km between Hirtshals in the west and Skagen in the east forming the northern-most Danish Skagerrak coast.

Two species of the nematode family Diplopeltidae are described from Skagerrak. The new genus Belgopeltula gen. nov. is proposed for Diplopeltula belgica Vincx & Gourbault, 1992 and is characterised by: amphidial fovea circular in female and double-loop-shaped in male; excretory pore located at the level of cephalic setae bases; oral opening on the dorsal side of the body; pharynx subdivided into strongly muscularised fusiform corpus and weakly muscularised narrow and long postcorpus; female didelphic with antidromously reflexed ovaries; supplements absent. Mudwigglus micramphidium sp. nov. is characterised by: a body of 0.6 mm long; cephalic sensilla 1.5 µm long; amphidial fovea loop-shaped, 8 µm long and 3.5 µm wide; gymnostom without cuticularised ring; tail elongate conoid, with subcylindrical distal part; terminal setae absent; spicules 15 µm long; gubernaculum present; two midventral precloacal setae. It is distinguished from M. macramphidium Leduc, 2013 in having shorter amphidial fovea, shorter spicules and presence of two precloacal setae. Redescription of Diplopeltis cylindricauda Allgén, 1932 is provided based on type material. Diplopeltula minuta Vitiello, 1972 is transferred to the genus Mudwigglus Leduc, 2013. Diplopeltis cylindricauda Allgén, 1932, Diplopeltula laminata Vitiello, 1972 and Diplopeltula cassidaignensis Vitiello, 1972 are transferred to the genus Pseudaraeolaimus Chitwood, 1951.
